CROSS-REFERENCE TO RELATED APPLICATION

This application is a National Stage entry of International Application No. PCT/GB02/00594, filed Feb. 11, 2002, the entire specification claims and drawings of which are incorporated herewith by reference.

The present invention relates to a camera rig, and particularly although not necessarily exclusively relates to a camera rig for use with a digital video camera.

Digital video cameras have become very popular due to their inherent advantages. These advantages include being able to download the shot film onto a personal computer. This allows the editing to be achieved easily and quickly.

As digital video cameras have become more popular over the last few years they have, due to increased understanding and better technologies, become smaller. This offers the advantage tat they are more easily transportable. However, there are a number of problems ted with small video cameras. One such problem is that it is difficult to shoot steady film. By film it is meant a series of images stored as a set of data. When film is taken by a camera that has not been supported it is usual to find that the resultant film shakes. This is due to the user moving the camera through the filming process. This phenomenon is generally termed camera shake.

It is known to attach cameras to free standing supports, often termed tripods. Tripods allow the camera to be supported and lace allows ease of taking film without any resultant camera shake. However, the problem with a tripod arrangement is that it is not particularly mobile and hence the resultant drawback encountered when filming in a confined area, or when the cameraman is required to move when filming. It is therefore a general aim of tie present invention to overcome or ameliorate the problem of camera shake whilst still gig the user of the camera the mobility to move the camera to different locations while filming.

Digital video cameras are also agile. In a busy working environment it is not uncommon for a camera to be dropped. Cameras are, in the main, not very robust and hence damage can often be incurred following it being dropped Therefore the present invention also seek to provide means to prevent damage should the camera be inadvertently dropped. The present invention particularly seeks to overcome the problem of damage to a camera through dropping or accident when the camera is not mounted on a tripod.

Digital video cameras also have further inherent disadvantages. These include the need for a user, if reasonable film is to be taken, to devote both hands to the camera Therefore if other accessories are required, such as a microphone or a light source a second person is required. Alternatively the cameraman must attempt to use both pieces of equipment simultaneously. This causes poor film quality. The present invention attempts to provide a solution to this problem, whilst still attempting to overcome the disadvantages of a tripod arrangement.

The present invention aims to address to the above problem by providing a camera rig which is capable of securely holding a camera and preferably one or more ancillary devices, and that in use or transport is easily moved.

Equipment for filming and photography is in the main expensive. Therefore it is also a preferred aim of the present invention to provide a cost effective frame structure may be easily manufactured, whilst being robust that solves the above problems.

According to a fist aspect of the present invention there is provided a camera rig suitable for handheld use comprising a frame and means to attach a camera inside of said frame.

The present invention therefore provides a mobile support for a camera, such as a digital video camera by providing a larger grip than a small camera and hence it is easier to hold steady. Therefore the user may shoot film in a steady manner. It is thus an advantage of the present invention that camera shake is either prevented or substantially reduced.

According to a second aspect of the present invention there is provided a camera rig comprising a frame capable of securely holding a camera and at least one further piece of equipment.

According to a third aspect of the present invention there is provided a camera rig comprising a frame and a camera support means mounted on the frame, the frame comprising at least two grip portions spaced from one another on opposite sides of the camera support means. The camera support means can be integral with the frame.

Desirably the frame comprises an outer frame and an inner frame mounted on the outer frame. Ideally the inner frame is provided with the camera support means. It is preferred that at least part of the inner frame on which the camera is mounted is moveable with respect to the remainder of the frame. Thus the position of the camera is adjustable with respect to the frame.

The outer frame can be substantially circular. Alternatively, the outer frame can be substantially elliptical. More preferably the inner frame comprises an H-frame. Conveniently the H frame may be fixed inside the outer frame.

In use, it is preferred that the camera is fixed to the centre bar of the H-frame. It is to be appreciated that various other shaped frames may be mounted within the circular frame, including one or more substantially horizontal or vertical bars.

In a preferred embodiment of the present invention the centre bar of the H-frame is capable of movement with respect to the remainder of the frame.

In an alternative arrangement the frame may be U-shaped with the camera support means mounted substantially in the centre of the U, dissecting the upwardly directed arms of the U. In this embodiment, the upwardly directed arms would each carry a grip portion.

Ideally a handle portion is provided to engage an opposite side of the frame to the camera support means. This arrangement enables a camera to be attached and removed from the support means more conveniently than when the frame is held by the grip portions alone. The handle may be provided with securing means which can pass through an aperture in the frame and the support means to engage the camera and hold it in engagement with said support means. These securing means could be a screw fixing or any other suitable means.

It is preferred that the frame is made from aluminium. This has advantages in that it is light and strong.

Alternatively, the frame may be made from a plastics material. One suitable plastics material is welded PVC, this and other suitable plastics materials can allow the frame to be of an inflatable construction. Not only does this result in a light weight frame to ease operation thereof but also this alleviates the likelihood of damage to the camera mounted on or in the frame in the eat of the frame being dropped. The frame may, alternatively, be made out of a hardened plastics material.

Preferably the camera rig comprises grip portions. Preferably said grip portions are located on the outer frame. Where the frame is inflatable, said grip portions are located substantially adjacent to the periphery of the frame, distal to the camera support mean. Further, when the frame is inflatable, the grip portions may consist of apertures through the frame.

In order that the present invention be more readily understood specific embodiments thereof will now be described with reference to the accompanying drawings in which,
